after looking at the tank some im wanting to add another 3-4" height wise, i wont be extending the glass just more room to work with the water level. i was going to use more 1x3 screw directly through it to the other 1x3 with 3.5" deck mate deck screws and wood glue. Think that will work
yes inside and out.... i was going to go 3/4"inside and 1/2" out but i was informed that the 1/2" outside will really yield no additional strength. So im going to go with a 1/4" sheet of fine grade for the outside so i can just stain it and trim it out. Has anyone used gelcoat to paint the inside of this tank before?
